Doc: Remove "Container keywords" section from containers.html

For foreach, we just mention that it is deprecated, and forever is not
actually directly related to Qt containers. Both macros are also
documented in qglobal.cpp, and the section title is not referenced
anywhere so this patch won't break any links.

Pick-to: 6.4
